17 Claims. (Cl. '-310) This invention relates to beds and sofas and inparticular is directed to the provision of improvements in supportingmeans for a bedspring whereby the same may be readily adapted for use asa bed or a sofa.

I have conceived of a means whereby a bedspring of suitable sturdinessmay be readily, easily and cheaply provided with a set of improvedsupports of relatively simple construction, said supports being easilyaflixed or removed, so that a structure can be made available withminimum expense which affords either seating or sleeping accommodations.

Accordingly, it is among the objects of this invention to rovideimproved supports for bedsprings characterized by relative simplicity ofconstruction, the supports being readily atfixable to the frames of abedspring so as to convert the bedspring into a structure that may beused both as a seat and as a bed.

Further objects and advantages will become apparent from the followingmore detailed description of my invention taken in connection with theaccompanying drawings wherein:

Fig. 11 is a cross sectional view showing another form of the inventionshown in Fig. 10.

In its fundamental aspects, the primary object of my Patented Get. 30,1956 invention is achieved by a demountable support for a bedspringwhich comprises a channel-like member having a bottom and side adaptedto receive the rail of a bedspring frame, said channel member havingmeans extending therefrom adapted for engagement by a clamping member, aleg depending from said channel to maintain said rail in elevatedposition, a clamping member mounted over said rail, the clamping memberhaving means adapted to engage the correlated means on the channel andtightening means whereby the rail and leg are clamped in rigid assembledrelationship.

Referring now to the drawings, and particularly with reference to Fig.1, the numeral 20 designates a tubular rail such as commonly used forthe type of flat-spring bedspring frames. The rail 20 is received inchannel member 22 comprising bottom 24 and walls 26. The leg 28, affixedto the bottom of the channel, maintains the bedspring in elevatedposition when the device is assembled. Member 22 is provided withoppositely disposed flanges 30 which extend outwardly from side walls26.

Clamping member 32 consists of a substantially C- shaped piece havinggenerally fiat side 34 fairing into lateral ends 36, the latter beingprovided with inwardly disposed flanges 38. As can be seen from thedrawings, when clamping member 32 is mounted over rail 2%, flanges 38engage flanges 30 of the channel piece 22. By tightening set screws 49,which extend through threaded bores in wall 36, the rail 20, channelmember 22, leg 28, and member 32 are clamped into rigid assembledrelationship.

U-shaped member 50 may be advantageously used in conjunction with mydevice as a centering means for bedspring rails of tubular or circularshape. With such rails it is of importance that set screws 40 clamp downupon the midpoint of the tubular rail. If the set screws strike the railoff-center, there is a likelihood that the rail will slip away from thescrews when under pressure thereby causing leg 28 to incline and buckle.When U-shaped member 50 is used in conjunction with my device to centertubular rails, the said member is nested within channel piece 22, asshown in Fig. 2, to receive tubular rail it prior to clamping. In thisinstance, ribs 52, projecting from U-shaped member 50, provided themember with a gripping surface and help take up clearances which mayexist between the rail and the channel piece 22.

By forming the bottom 24 of channel piece 22 with a recess 56 therein, Iprovide a means whereby the leg 28 may be aflixed to bottom 24 by meansof nuts 53 and 69, the latter being received in the recess so as not tointerfere with the resting of the rail on the bottom for rigid clamping.As can be seen from the drawings, especially Fig. 1, the rail, whenpositioned for clamping, overrides nut 64) and the threaded end of leg28, which are retained in recess 56 and do not project above the topsurface 2 of the channel.

In Fig. 3, the structure is shown in assembled relationship with anangular rail. In this case, the U-shaped piece 50 is set in channelpiece 22 to provide a rest for the horizontal web 44 of the angularrail. In Fig. 4, a wooden block 46 is shown as the rest or support forweb 44 instead of piece 50. In lieu of piece 50 or block 4-6, thechannel piece 22 may be provided, as shown in Fig. 6 with one or morevertical disposed and adjustably positionable set screws or bolts 48 toprovide support for horizontal web 44.

If the horizontal web 44 of an. angular rail 42 is, as seen in 'Fig. 7,wide enough to rest on one of the flanges 30 of 22 when the vertical weblies along the opposite vertical wall of 22, a separate support for thehorizontal web 44 may be dispensed with.

As shown in Fig. 5, the side of the rail, instead of the top thereof,may be the part to which the structure of this invention is clamped. Inthis modification leg 28 depends from a side 26' of channel piece 22'instead of from the bottom of the channel piece as in the prior forms.The side 26' may have a recess 56 akin to 56.

The structure shown in Pig. 8 is akin to that of Fi 2 except for thecross section of the rail 20' which, in this case is oval.

As shown in Fig. 9, the embodiment of the invention comprises a channelpiece 23, having a bottom 25 and walls 27. The bottom is provided with arecess 57. Walls 27 terminate in outwardly extending flanges 31. Atubular rail 20, is centered and pinned by projections 59 punched upfrom bottom 25 when clamping member 32 is placed in operative positionakin to that position in Figs. 1 and 2.

As shown in Fig. 10, channel piece 70 has a bottom 72 which is recessedas at 74. A wooden leg 76 may be secured to the underside of the recess74 by means of hanger bolt 78. v Hanger bolt 78 is secured to the leg 76by the wood screw section 80 thereof. The externally disposed portion ofhanger bolt 78 is provided with machine screw threads as at 82 so thatthe leg can be secured to the channel piece by engagement with thethreads of orifice 84, and, if desired, further by locknut 86. Orifice84 may, if desired, be left unthreaded, in which case, nut 86cfifectuates the holding of the leg to the channel.

As shown in Fig. 11 channel piece 90 has a bottom 92 which is recessedas at 94, the recess having a centrally disposed downwardly extendingtubular extension 96. Wooden leg 98 is secured to piece 90 by means ofhanger bolt 100. The hanger bolt is secured to the wooden leg by meansof the wood screw section 102 thereof. The upper face of leg 98 isrecessed to receive 96. The latter may be threaded internally as shown,to receive the machine screw threaded portion 106 of hanger bolt 100.Nut 108 may be used to lock the hanger bolt in position.

It will be understood that the terms horizontal and vertical as usedherein have reference to directions with respect to the normal positionof a bedspring when in use.

It will be apparent from the foregoing description of this inventionthat the device basically comprises a channel piece which serves toreceive the rail of a bedspring frame, the channel piece havinglongitudinally extending flanges; a leg either permanently (by weldingor peening or other suitable means) affixed, or demountably aflixable tothe channel piece, also optionally means for centering and/ orpositioning the rail when received in the channel, a C-shaped memberthat completes coverage or engirdling of the rail and has means forengaging the flanges of the channel piece, and means to tighten the railwhen received in the channel, the cover member and channel into clampedrigid assembled relationship.

It will be further evident that the channel piece can readilyaccommodate legs of any length and any shape or dimension of wood orsteel with a threaded bolt inserted, thereby allowing for a wide varietyof heights, as well as a wide variety of uses.

It will be understood that the foregoing description of the inventionand the embodiments illustrated are merely illustrative of theprinciples thereof. Accordingly, the appended claims are to be construedas defining the invention within the full spirit and scope thereof.
